Orange striped stoneflies wanted

The Riverfly Partnership are looking for specimens of the Orange striped stonefly. This large stonefly now has a new scientific name Perlodes mortoni, formerly it was Perlodes microcephalus. Apparently the type found in Britain is now considered to be a seperate species from that found in Europe. I have found the nymphs of this large stonefly in every sample from the mainstem so the adults should be plentiful on the riverbanks soon. If you are interested in collecting and sending samples you will find the details here . They recommend preserving the samples in gin or vodka but I’m sure the more readily available local spirits such as Macallan or Glenfiddich will do just as well! I have plenty sample tubes (small ones) if required.

For the avoidance of doubt and for the benefit of the odd individual who can’t tell a spoof post from the genuine article rest assured that this is in the latter category.
